INTRODUCTION: Acetic acid (acetate) occurs in a wide range of foods and beverages, and in many other materials such as paper, pharmaceuticals and industrial products. In the wine industry it is one of the most important quality parameters and is measured throughout the entire vinification process. This advanced kit (K-ACET) benefits from greatly increased shelf life as the acetyl-coenzyme A synthetase (ACS) is supplied as a highly stable ready-to-use ammonium sulphate suspension, rather than as a lyophilised powder. Polyvinylpyrollidone (PVP) has also been incorporated into the assay to prevent interference from particular tannins found especially in red wines. This kit is recommended for manual analysis, while two additional kits have been optimised for auto-analysis applications; K-ACETAF has extended calibration linearity up to 30 μg/mL (in the final assay), and also benefits from a stabilisation system that significantly reduces the rate of deterioration (increase in absorbance) of prepared reagent, a problem exhibited by some other products; K-ACETAK is a new assay format based on acetate kinase. As an indicator reaction is not involved in this case, a change in absorbance stoichiometric with the amount of acetic acid is achieved, resulting in excellent linear calibration (R2 > 0.999). KITS: Kits suitable for performing 53 determinations are available from Megazyme. The kits contain the full assay method plus: Bottle 1: Buffer (30 mL, pH 8.4) plus L-malic acid and sodium azide (0.02 % w/v) as a preservative. Stable for > 2 years at 4°C. Bottle 2: (x2) NAD+ plus ATP, PVP and CoA. Freeze dried powder. Stable for > 5 years at -20°C. Bottle 3: L-Malate dehydrogenase plus citrate synthase suspension, 1.1 mL. Stable for > 2 years at 4°C.
